Dreamvault

Dreamvault can't be countered.
Dreamvault has protection from everything
except itself.
At the beginning of each upkeep, each player
puts a dream counter on Dreamvault. Then all
players draw cards equal to the number of dream counters on Dreamvault, and sacrifice half that
many permanents rounded up.
Any player may exile his or her graveyard and all permanents he or she controls to destroy
Dreamvault.
When a dream is all you have, holding it and losing it are both suffering.
